Solution

1. Preparation

Gather tools: socket set, wrenches, OBD-II scanner, flashlight.
Ensure the vehicle is parked on a flat surface, and the engine is turned off and cooled down.

2. Inspect and Replace Belts

Inspect the Serpentine Belt:
- Visually check the belt for cracks, fraying, or glazing.
- Feel for any signs of looseness or slippage.
Replace if Necessary:
- If the belt is worn, loosen the tensioner using a wrench and remove the old belt.
- Install the new serpentine belt, ensuring it follows the correct routing path.
- Tighten the tensioner back to specification.

3. Inspect Other Rubber Components

Check Engine Mounts and Hoses:
- Inspect engine mounts for signs of deterioration or wear.
- Check rubber hoses for leaks, cracks, or signs of expansion.
Replace Damaged Parts:
- If any components are found damaged, replace them with OEM or quality aftermarket parts.

4. Clean Up

Remove Residue:
- If any burned rubber residue is present, clean the affected areas with a degreaser and a cloth.
Dispose of old parts properly.
